Key Features
- Genuine OEM Sealing Integrity — manufactured to Husqvarna's material and compression specifications, ensuring the tank cap seals correctly and maintains proper pressure containment within the dust extractor.
- Complete Assembly — supplied as a full Tank Cap Assembly, so all mating components arrive together for a straightforward, direct installation.
- Confirmed S26 and S36 Fitment — engineered specifically for the S26 and S36 dust extractors, matching original thread pitch, cap diameter, and retention design.
- Dust Containment Performance — a properly seated tank cap prevents bypass leakage and maintains the negative pressure necessary for effective dust extraction during cutting and grinding operations.
- Operational Safety — a secure, correctly fitting tank cap prevents accidental release of collected dust or slurry, helping operators stay compliant with dust exposure control requirements on the jobsite.
The tank cap assembly seals the collection tank on the dust extractor, maintaining the airtight environment the machine needs to generate and sustain suction. When the cap fits correctly, the extractor draws dust efficiently and contains collected material safely between emptyings. A damaged, worn, or ill-fitting cap allows air to bypass the seal, reducing suction performance and risking uncontrolled release of captured dust — undermining both extraction efficiency and on-site dust control compliance.
